* Make endian-conversion macros always return correct types (bug 16458).Joseph Myers2017-01-111-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 16458 reports that the endian-conversion macros in <endian.h> and <netinet/in.h>, in the case where no endian conversion is needed, just return their arguments without converting to the expected return type, so failing to act as expected for a macro version of a function. (The <netinet/in.h> macros, in particular, are described with prototypes in POSIX so should act like correspondingly prototyped functions.) Where previously this was a fairly obscure issue, it now results in glibc build with GCC mainline breaking for big-endian systems: nss_hesiod/hesiod-service.c: In function '_nss_hesiod_getservbyport_r': nss_hesiod/hesiod-service.c:142:39: error: '%d' directive output may be truncated writing between 1 and 11 bytes into a region of size 6 [-Werror=format-truncation=] snprintf (portstr, sizeof portstr, "%d", ntohs (port)); ^~ nss_hesiod/hesiod-service.c:142:38: note: using the range [1, -2147483648] for directive argument snprintf (portstr, sizeof portstr, "%d", ntohs (port)); ^~~~ nss_hesiod/hesiod-service.c:142:3: note: format output between 2 and 12 bytes into a destination of size 6 snprintf (portstr, sizeof portstr, "%d", ntohs (port)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The port argument is passed as int to this function, so when ntohs does not convert the compiler cannot tell that the result is within the range of uint16_t. (I don't know if in fact it's possible for out-of-range values to reach this function and so get truncated as strings without this patch or as integers with it.) This patch arranges for these macros to use identity functions to ensure appropriate conversions while having warnings for implicit conversions of function arguments that might not occur with a cast. Tested for x86_64 and x86; with build-many-glibcs.py with GCC 6; and with build-many-glibcs.py with GCC mainline for powerpc to test the build fix.

* inet: Make IN6_IS_ADDR_UNSPECIFIED etc. usable with POSIX [BZ #16421]Florian Weimer2016-12-091-23/+21
| | | | | | Previously, under some feature test macros and compilers, the macros were defined, but references undefined struct members in their implementation.
* Installed-header hygiene (BZ#20366): conditionally defined structures.Zack Weinberg2016-09-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several network-related structures are defined conditionally under __USE_MISC, but unconditionally used by other headers. The path of least resistance is usually to condition the uses on __USE_MISC as well. * sysdeps/mach/hurd/net/if_ppp.h * sysdeps/unix/sysv/linux/net/if_ppp.h: Only define struct ifpppstatsreq and struct ifpppcstatsreq if __USE_MISC is defined, to ensure struct ifreq is declared. * inet/netinet/ether.h: Condition all function prototypes on __USE_MISC, to ensure struct ether_addr is declared. sys/socket.h defines struct osockaddr only under __USE_MISC, whereas protocols/talkd.h requires it unconditionally. Here it doesn't make sense to condition the entire body of protocols/talkd.h on __USE_MISC. Rather than complicate sys/socket.h with a __need macro or duplicate the definition, I am introducing a new concept: tiny headers named bits/types/TYPE.h that define TYPE and nothing else. This can, I hope, ultimately replace *all* the __need macros. The guard macro for such headers will be __TYPE_defined, just in case application or third-party library code is looking at them. * socket/bits/types/struct_osockaddr.h: New header. * include/bits/types/struct_osockaddr.h: New wrapper. * socket/Makefile: Install the new header. * socket/sys/socket.h, inet/protocols/talkd.h: Refer to bits/types/struct_osockaddr.h for the definition of struct osockaddr.
* Installed-header hygiene (BZ#20366): obsolete BSD u_* types.Zack Weinberg2016-09-231-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The types u_char, u_short, u_int, u_long, ushort, uint, ulong, u_int8_t, u_int16_t, u_int32_t, u_int64_t, quad_t, and u_quad_t are BSDisms that have never been standardized. While glibc should continue to *provide* these types for compatibility's sake, its public headers should not use them. The meat of this change was mechanically generated by the following shell command: perl -pi~ -e ' s/\b(__)?u_char\b/unsigned char/g; s/\b(__)?u_?short\b/unsigned short/g; s/\b(__)?u_?int\b/unsigned int/g; s/\b(__)?u_?long\b/unsigned long/g; s/\b(__)?u_int8_t\b/uint8_t/g; s/\b(__)?u_int16_t\b/uint16_t/g; s/\b(__)?u_int32_t\b/uint32_t/g; s/\b(__)?u_int64_t\b/uint64_t/g; s/\b(__)?u_quad_t\b/uint64_t/g; s/\b(__)?quad_t\b/uint64_t/g; ' $(grep -lE -e '\<((__)?(quad_t|u(short|int|long|_(char|short|int([0-9]+_t)?|long|quad_t))))\>' \ $(grep -LE '\<(_(SYS|BITS)_TYPES_H|rpc/(rpc|rpc_msg|types|xdr)\.h)\>' \ $(find . \( -false $(sed 's/^/-o -name /' all-installed-headers) \ \) -printf '%P\n' | sort -u))) where 'all-installed-headers' was a list of the basenames of all installed header files, manually extracted from the Makefiles. Non-installed wrapper headers in include/ are also adjusted, for consistency. I then manually fixed up indentation and line-wrapping. sys/types.h and bits/types.h are excluded because they must continue to define the u_* types (under __USE_MISC) for compatibility with applications. They do not use these types themselves. All headers that (transitively) include rpc/types.h are also excluded, for three reasons. First, the u_* types are defined by rpc/types.h, unconditionally (not just under __USE_MISC) so they are logically part of the SunRPC API. Second, many of those headers appear to be machine-generated. Third, it's my understanding that we are getting rid of as much of SunRPC as possible in the near future. (The one file under sunrpc/ that's touched, sunrpc/rpc/rpc_des.h, does *not* include rpc/types.h. This may itself be a bug.) After changing from u_intNN_t to uintNN_t, a number of headers now need to include stdint.h to pick up those types. It might be more hygenic, namespace-wise, to use __uintNN_t instead, but none of these headers are bound by ISO or POSIX to do so, and it's unlikely that anyone using them will be bothered. (The two files that were using __-prefixed versions of the u_types, sysdeps/mach/hurd/net/route.h and sysdeps/unix/sysv/linux/net/route.h, both already also contained uses of the unprefixed versions.) Some of these files directly included features.h and/or sys/cdefs.h, which I removed, as the style generally seems to be to let sys/types.h do that for us. (This does not change the set of definitions exposed by any header; sys/types.h unconditionally includes both features.h and sys/cdefs.h.) One file included asm/types.h unnecessarily. * bits/in.h, gmon/sys/gmon.h, inet/netinet/igmp.h * inet/protocols/routed.h, inet/protocols/talkd.h * inet/protocols/timed.h, io/fts.h, nptl_db/thread_db.h * resolv/arpa/nameser.h, resolv/resolv.h, sunrpc/rpc/rpc_des.h * sysdeps/generic/netinet/if_ether.h * sysdeps/generic/netinet/in_systm.h * sysdeps/generic/netinet/ip.h, sysdeps/generic/netinet/tcp.h * sysdeps/gnu/netinet/ip_icmp.h, sysdeps/gnu/netinet/tcp.h * sysdeps/gnu/netinet/udp.h, sysdeps/mach/hurd/net/ethernet.h * sysdeps/mach/hurd/net/if_arp.h * sysdeps/mach/hurd/net/if_ppp.h * sysdeps/mach/hurd/net/route.h, sysdeps/mach/sys/reboot.h * sysdeps/unix/sysv/linux/bits/in.h * sysdeps/unix/sysv/linux/net/ethernet.h * sysdeps/unix/sysv/linux/net/if_arp.h * sysdeps/unix/sysv/linux/net/if_ppp.h * sysdeps/unix/sysv/linux/net/if_shaper.h * sysdeps/unix/sysv/linux/net/route.h * sysdeps/unix/sysv/linux/netinet/if_ether.h * sysdeps/unix/sysv/linux/netinet/if_fddi.h * sysdeps/unix/sysv/linux/netinet/if_tr.h * sysdeps/unix/sysv/linux/netipx/ipx.h * sysdeps/unix/sysv/linux/sys/acct.h * include/arpa/nameser.h, include/resolv.h: Change all uses of u_char to unsigned char, u_short and ushort to unsigned short, u_int and uint to unsigned int, u_long and ulong to unsigned long, u_int8_t to uint8_t, u_int16_t to uint16_t, u_int32_t to uint32_t, quad_t to int64_t, and u_int64_t and u_quad_t to uint64_t. * mach/sys/reboot.h: Remove two casts of integer literals to the types they already have. * bits/in.h: Correct error in description of IP_MULTICAST_LOOP. * sysdeps/unix/sysv/linux/bits/in.h: Likewise. * sysdeps/unix/sysv/linux/netinet/if_ether.h: Change a comment from referring to 'unsigned char' to 'uint8_t' for consistency with the macro definition below. * gmon/sys/gmon.h, inet/netinet/igmp.h, inet/protocols/talkd.h * io/fts.h, resolv/arpa/nameser.h, resolv/resolv.h * sunrpc/rpc/rpc_des.h, sysdeps/generic/netinet/ip.h * sysdeps/gnu/netinet/tcp.h, sysdeps/gnu/netinet/udp.h * sysdeps/mach/hurd/net/if_ppp.h, sysdeps/unix/sysv/linux/net/if_ppp.h * sysdeps/unix/sysv/linux/sys/acct.h * include/arpa/nameser.h, include/resolv.h: Fix indentation disrupted by mechanical edits. * inet/protocols/talkd.h, resolv/arpa/nameser.h * sysdeps/generic/netinet/in_systm.h * sysdeps/gnu/netinet/ip_icmp.h, sysdeps/gnu/netinet/tcp.h * sysdeps/gnu/netinet/udp.h * sysdeps/unix/sysv/linux/net/ethernet.h * sysdeps/unix/sysv/linux/net/if_arp.h * sysdeps/unix/sysv/linux/net/if_ppp.h * sysdeps/unix/sysv/linux/net/if_shaper.h * sysdeps/unix/sysv/linux/netinet/if_fddi.h * sysdeps/unix/sysv/linux/netinet/if_tr.h * sysdeps/unix/sysv/linux/netipx/ipx.h * sysdeps/unix/sysv/linux/sys/acct.h Include stdint.h for uintNN_t definitions.

* Installed-header hygiene (BZ#20366): Simple self-contained fixes.Zack Weinberg2016-09-232-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some headers did not include all of their prerequisite headers. * rpcsvc/nislib.h: Include rpcsvc/nis.h. * sysdeps/unix/sysv/linux/netrose/rose.h: Include sys/socket.h and netax25/ax25.h. <endian.h> only defines BYTE_ORDER, BIG_ENDIAN, LITTLE_ENDIAN, etc. under __USE_MISC; glibc's headers should use __BYTE_ORDER, __BIG_ENDIAN, __LITTLE_ENDIAN, etc. instead. * inet/netinet/icmp6.h, inet/netinet/ip6.h * resolv/arpa/nameser_compat.h: Use __BYTE_ORDER etc. instead of BYTE_ORDER etc. sys/types.h only conditionally defines caddr_t and clockid_t. * sysdeps/unix/sysv/linux/sys/quota.h: Use __caddr_t instead of caddr_t. * sysdeps/unix/sysv/linux/sys/timerfd.h: Use __clockid_t instead of clockid_t. Remove a #warning that was the sole actual problem with using sys/ipc.h without _GNU_SOURCE/_XOPEN_SOURCE. * sysvipc/sys/ipc.h: Remove unnecessary #warning. _LIBC, __USE_XOPEN2K8, and __STDC_VERSION__ are not always defined. It seems to me that _LIBC should not appear in installed headers, but avoiding that for argp specifically would require more surgery than feels appropriate for this patch set. It's possible that "#ifdef _LIBC" would be sufficient, but I wanted to be conservative. All three versions of bits/socket.h want to know whether __flexarr will produce a real flexible array member -- specifically, one that doesn't alter sizeof(the structure containing it). They were testing for this with a complicated #if condition that did not agree with sys/cdefs.h and that tripped -Wundef warnings under -std=c90. I added a new macro to sys/cdefs.h, __glibc_c99_flexarr_available, which reveals exactly what these headers want to know. I also took the opportunity to flatten the rather messy conditional nest defining __flexarr. * argp/argp.h: Check whether _LIBC is defined before expanding it. * posix/glob.h: Check whether __USE_XOPEN2K8 is defined instead of expanding it. * misc/sys/cdefs.h: Tidy up conditional nest defining __flexarr. Define __glibc_c99_flexarr_available to 1 when the compiler supports C99-compatible flexible array members, 0 otherwise. * sysdeps/unix/sysv/linux/bits/socket.h * sysdeps/mach/hurd/bits/socket.h * bits/socket.h: Use __glibc_c99_flexarr_available in definitions of struct cmsghdr and CMSG_DATA.
* Fix macro API for __USE_KERNEL_IPV6_DEFS.Carlos O'Donell2016-06-021-7/+7
| | | | | | | | | | | | | | | | The use of __USE_KERNEL_IPV6_DEFS with ifndef is bad practice per: https://sourceware.org/glibc/wiki/Wundef. This change moves it to use 'if' and always define the macro. Please note that this is not the only problem with this code. I have a series of fixes after this one to resolve breakage with this code and add regression tests for it via compile-only source testing (to be discussed in another thread). Unfortunately __USE_KERNEL_XATTR_DEFS is set by the kernel and not glibc, and uses 'define', so we can't fix that yet.

* Add netinet/in.h values from Linux 4.2.Joseph Myers2015-09-011-0/+2
| | | | | | | | | | | | | | This patch adds new constants from Linux 4.2 to netinet/in.h: IPPROTO_MPLS and IP_BIND_ADDRESS_NO_PORT (both in include/uapi/linux/in.h in Linux; one directly in netinet/in.h, one in bits/in.h in glibc). Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * inet/netinet/in.h (IPPROTO_MPLS): New enum value and macro. * sysdeps/unix/sysv/linux/bits/in.h (IP_BIND_ADDRESS_NO_PORT): New macro.

* Complete _BSD_SOURCE / _SVID_source followup cleanup.Joseph Myers2014-02-211-5/+5

This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.

* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-121-1/+1

The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

* BZ #16529: Fix pedantic warning with netinet/in.h.Carlos O'Donell2014-02-061-1/+1
| | | | | | | | | | | | | | | | | When compiling with pedantic the following warning is seen: gcc -Wall -pedantic -O0 -o test test.c In file included from test.c:3:0: /path/inet/netinet/in.h:111:21: warning: comma at end of \ enumerator list [-Wpedantic] IPPROTO_MH = 135, /* IPv6 mobility header. */ ^ It is valid C99 to have a trailing comma after the last item in an enumeration. However it is not valid C90. If possible glibc attempts to keep all headers C90 + long long without requiring C99 features. In this case it's easy to fix the headers and it removes the warning seem with -pedantic.

* Coordinate IPv6 definitions for Linux and glibcCarlos O'Donell2013-09-061-29/+40
| | | | | | | | | | This change synchronizes the glibc headers with the Linux kernel headers and arranges to coordinate the definition of structures already defined the Linux kernel UAPI headers. It is now safe to include glibc's netinet/in.h or Linux's linux/in6.h in any order in a userspace application and you will get the same ABI. The ABI is guaranteed by UAPI and glibc.
